RICHARD WHARTON, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF FIVE-EIGHTHS TO JAMES B. PATTERSON, OF SAME PLACE.

D'OUP-HEDDLE FORALOOMS'.

SPECIFICATION forming part of Letters Patent No. 456,180, dated July 21, 1891.

Application filed February 2, 1891. Serial No. 379,894- (No model.)

To all whom it may concern.-

Be it known that I, RICHARD WHARToN, a citizen of the'United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Doup-Heddles for Looms for Cross-Weaving, of which the following is a specification.

My invention relates to doup-heddles used for cross-weaving; and it consists in constructing the full heddle of flat sheet metal, slotted and provided with a perforated cross-bar midway in the length of the slot, and a half-heddle, made of round or fiat wire and having an eye at the top, as is fully illustrated in the accompanying drawings, in Which- Figure 1 is a view of the full heddle, as cut from sheet metal, and before the cross-bar is soldered on. Fig. 2 is an edge view'of Fig. 1, with the cross-bar soldered on. Fig. 3 is a view of the full heddle, as cut from sheet metal, and having a cross-bar midway in the slot. Fig. 4 is a view of Fig. 3, with the crossbar perforated and swaged to form an eye. Fig. 5 is an edge view of Fig. 4. Fig. 6 is a cross-section of Fig. 4 at the line X Y. Fig. 7 is a cross-section of Fig. 2 at the line X Y. Fig. 8 is a view of the detached cross-bar. Figs. 9 are views of the half-heddle, made of round wire. Figs. 10 are views of the halfheddle, made of fiat wire.

Similar letters in the drawings refer to like parts.

A represents the full heddle, which may becut from any kind of sheet metal, but I prefer to make them from tempered sheet steel, and to cut them as shown in Fig. 3, with a cross-bar D. In this bar D is cut a hole E, and after the hole E is cut the bar D is s'waged so as to throw half of the bar on each side, as shown in section, Fig. 6.

B is the half-heddle, and it may be made of round wire, as shown in Fig. 9, or of fiat wire, as shown in Fig. 10. These half-heddles have an eye at the top for the crossing warp-thread, and an eye at the bottom by which they are strung in heddle-frames.

Constructing the full heddle of a wide piece of metal and slotting out the center, enables me to make a thin, strong, and light heddle. A greater number of thin heddles can be put into the inch than thick ones, anda wide heddle will not chafe the'yarn as much as a narrow one.

The full heddles A are strung in heddleframes of ordinaryconstruction, havingstringing-bars at top and bottom. Thehalf-heddles B are strung in frames having a stringing-bar at the bottom only. The top end of heddle B is passed through the eye E in the full heddle A, and the eye in the half-heddle is made to project a little above the bar D. When the heddle A is cut as shown in Fig. 1, the cross-bar D is made of half-round wire and in form as shown in Fig. 8, and when soldered on, as shown in Fig. 2, and section, Fig. 7.

To apply my improved doup-heddle to looms, the doups are strung in heddle-frames of ordinary construction, such as are used for ordinary wire heddles, and the warp-threads are drawn in my improved doup, as is customary in cross-weaving. The heddles are operated, as usual, in looms for cross-weaving.

Having as above fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

A doup-heddle for cross-weaving, consisting of a full heddle, made from flat sheet metal and having a longitudinal slot, and a perforated cross-bar, in combination with a halt heddle adapted to pass through the perforation of said full heddle, as described, and for the purpose specified.
